You're going to need:

• Linux or macOS — Windows may work, but is unsupported.
• Ruby, version 2.3.1 or newer
• Bundler — If Ruby is already installed, but the bundle command doesn't work, just run gem install bundler in a terminal.

NOTE: The original Slate repository requires that you fork the repo to build your docs. Instead, we've vendored the repo into our docs. To develop our API locally, execute the following:

bundle install
bundle exec middleman server

You can now see the docs at http://localhost:4567.

Slate isn't exactly a library that you can npm install or npm update. If Slate releases an update that we need, currently, it will require us to download their repo again, and replace the src files (but don't delete our index.html.md!)
